^aLC/UV values quantified using an external calibration approach.

^bThe mass fraction values are the average ± standard deviation of ten measurements for each calibrant, candidate SRM 3389, and MIGS-1 control solutions. In the cases of LC/MS, the candidate SRM 3389 was measured nine times.

^cLC/MS values quantified using ginsenoside Rh1 for the internal standard calibration approach.
